The Scheule referred to in these Letters Patent and making part of the same.

To all whom tt may concern:

Be it known that I, ALPHEUs BIeoNr, of Canal Winchester, in the county of Franklin, and State of Ohio, have invented anew and useful Improvement in Machines for Scribing Mortises and Tenons for Sash, and other timber; and I do hereby declare the following to bea Tull, clear, and exact descriptiomthereof, reference being had to the accompanying drawings of' the same, which make part of this specitication, and

Figure 1 represents-'ra view, vin perspective, of a machine embracing my improvements, the carriage being removed from its ways, and turned down at the side of the machine to show the several parts more clearly. t

Figure 2 represents a similar view, the carriage being in its proper place.

Figure 3 represents a transverse section of the carriage, showing the adjustable transverse supportingbars. y t

Figure 4 represents a section through one of the scn'bing-tools, and its adjustable carrying-block, showl ing the springscribing-tool.

My invention relates to a machine for scribing and laying out check-rails and stiles for sash and other work, and consists in the arrangement of a horizontal l carriage, provided with transverse adj ustabie supporting-bars, and made to slide between an upper and a lower series of scribing-tools, one of said supportingbars being fixed, and the other adjustable, for the purpose ol' scribing ,both sides ot' the rails and stiles or other timber, at one and the same movement of carriage.

. In the accompanying'.drawings;

A represents the frame, upon which the several parts ot' the machine are supported and arranged.

'Ihe scribing-tools are arranged upon two horizon- ,tal bars, B and C, placed parallel to each other, one (B) above the frame, and the other (C) in the same vertical line, below the top thereof.

The former is mounted upon semi-elliptical springs D, one at each end, and is mmleadjustable to elevate of two vertical screw-bolts, E, passing through the springs D and each end of the' bar B, and secured in each end of'. the top timbers of, the frame by nuts 112 and regulated by adj listing-nuts F, which clamp said.V har, and the latter 4is fixed beneath the end-timbersl of the frame by the same screw-bolts E, by which-the upper bar is secured.

These bars are' provided with longitudinal slots a, within which the cutter-blocks G- are secured.

These blocks are of cast-iron, provided with tongues b, so as to it wit-hin the slots c, and are clamped by thumb-screws c, by which they may be adjusted in in the thickness of the material, and thereby avoid such adjustment by screws as heretofore. These scribing-tools'may be arranged in pairs in the same blocks, as well as single, as may be desired.

Between the upper and lower series of scribing tools, the horizontal carriage H is arranged, so as to slide back and forth upon ways I at each end thereof, which are of such height as to bring the upper sides of the bars J, upon which thematerial is supported,

on a level, or thereabouts, with the upper faces of the lower scribing-tool blocks G, so as to present the lower side of the material to the lower tools,.while the upper, scribers are adjusted to mark the upper face of the materia-l.

These supporting-bars J are placed transversely within the frame of the carriage H, and secured to the side-rails thereof, so as to admit of their adjustment nearer to or further from each other, according to the length of Jthe material being laid out, and are provided with shoulders K, against which the material is supported, while the end-bar, H', -of the frame of the carriage, being elevated above the supporting. bars, serve as gauges for the material from which the scribing-tools are adj usted.

The movement ot' the carriage-H upon its ways I is effected by means of its connection with a rockshaft, L, secured to the front side of the frame through arms M, projecting therefrom, and connected to horizontal arms N, pivoted to the end-bars H of the carriage.

The rock-shaft Lis connected to a treadle, O, byl a link, t', and arm j, said arm being also connected to a spring, P, secured beneath the frame, so that the action of the foot of the operator upon the treadle will force the carriage inward, so as to carry the material between the upper-and lower scribers, and upon releasing the pressure upon the treadle, the spring brings the carriage back, which motion is limited by the treadle O coming in contact with theunder side ofthe rock-shaft L, as shown in g. 2.

The operation of scribing the Stiles and rails of sash consists simply in placing and holding them against -the shoulders K ef the transverse bars J their ends resting against tbe right-baud gauging-bar H' of the frame, and zidjustiug the sliding-blocks G, with their tools, to lay off the. proper marks4 llie nmrkers Amuy be arraugedlto scribe the checkrails, by lim-'ing` two double cutters in the lower bar G `and two in the upper, :nid a double cutter, G', is arranged in the lower bar to scribe the lnnntin. I lie single cutters at the endsof the bars are to layoff the mortises. f

Haviut;l thus described my invention,

I claiml. The upper and lower sets of scribing-tools f, in combination with a horizontal carriage, H, located and made to slide between said marking-tools, in 'the man-4 ner and for the purpose describe-(1.

2. The combination of the fixed and adj nstable hor izontnl supporting-bars B C, the adjustable blocks G, the adjusting-screws E, ar d snpporting-springs D, with a horizontal slidingr carriage, H, having adj nstable transverse bars J, the whole constructed and arranged to operate a-s described.
